Mercury's surface in "enhanced color," a color scheme created to emphasize color differences. This is not what Mercury would look like to the human eye, but by applying mathematical analysis to images, color differences can be accentuated beyond those visible to a person.
Mount Rushmore National Memorial under construction.
The workers had to endure conditions that varied from blazing hot to bitterly cold and windy. Each day they climbed 700 stairs to the top of the mountain to punch-in on the time clock. Then 3/8 inch thick steel cables lowered them over the front of the 500-foot face of the mountain in a "bosun chair." Despite the dangers, no one was killed during the project.
Otters in Glacier Bay National Park and Preserve, Alaska.
The sea otter population of Glacier Bay has increased dramatically in the past 20 years. Ecologists consider sea otters a keystone species here. Otters consume vast quantities of clams, urchins, crabs, and other invertebrates and their presence creates ripples through the ecosystem. NPS photo.
Every day someone like you becomes a wildland wildfire fighter, a teacher, a trail-builder, a museum curator, or a park ranger. Discover your opportunities in national parks. Come to play. Come to learn. Come to serve. Develop your environmental leadership skills. Find a job. Be the next generation to preserve and protect these great places.
With more than 80% of Americans living in urban areas, urban parks are more important than ever. The father of American landscape architecture, Frederick Law Olmsted, said of urban parks:
It is one great purpose of the Park to supply to the hundreds of thousands of tired workers, who have no opportunity to spend their summers in the country, a specimen of God's handiwork that shall be to them, inexpensively, what a month or two in the White Mountains or the Adirondacks is, at great cost, to those in easier circumstances.

WASHINGTON – On Tuesday, June 26, Secretary of the Interior Ken Salazar will hold a teleconference with reporters to discuss next steps in planning for potential energy exploration in the U.S. Arctic, including through the 2012-2017 Five Year Program, which will be released in the coming days. Joining the Secretary on the call will be Deputy Secretary David J. Hayes and Bureau of Ocean Energy Management (BOEM) Director Tommy Beaudreau.
Salazar and Hayes are in Trondheim, Norway to continue their ongoing dialogue with international counterparts, government officials and oil and gas industry leaders to help inform the safe and responsible development of domestic offshore energy resources, including plans to expand production in the U.S. Arctic. On Tuesday morning, Salazar and Hayes will participate in an Arctic energy roundtable and on Wednesday they will participate in a ministerial forum on offshore drilling safety, including best practices developed in the United States. These discussions and meetings are part of the Obama administration's commitment to expanding safe and responsible production of our domestic resources while ensuring the strongest possible safety and environmental oversight of offshore oil and gas activities on the U.S. Outer Continental Shelf.
